That is, instead of properly reaping adopted processes, it's probably expecting another init process to do that job, and rightly so.

deskbar should probably detect their extension and execute the relevant command as opposed to opening the file for editing.

Your expectations are reasonable considering the property name, but

They cannot accept any less than 100 percent of their expectations being met.

Furthermore, how come there's a PR open since 3 months, at what seems to be the authoritative repo for Svelte?

You will be disrupted by this first issue. It is natural to expect relative references to be resolved against the .sass/.scss file in which they are specified (like in regular .css files).

The natural assumption is that this is because a) it is the best package manager, and b) the JavaScript community is the most energetic and productive.

When the message say function was called outside component initialization first will look at my code and last at my configuration.

What I believe should happen is the Svelte compiler should, when a promise is passed to onMount, realise that a promise has been passed, and await the result of the function to be used as the onDestroy function. i.e, it should behave the exact same way for an async function as it does for a non-async function (if this is possible)
